PIPE-CLEANI SPECIFICATION forming part of Letters Patent No. 351,500, dated October 26, 1886.

Application filed January 20, 1886.

To all whom it may concern:

Be it known that I, WILLIAM HAMILTON DEGGES, a citizen of the United States, residing at \Vashingtomin the District of Colum- 5 bia, have invented certain new and useful Improvements in Pipe-Cleaning Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invent-ion relates to devices for the "cleansing of tobacco-pipes, cigar-holders, cigarette-holders, and the like.

The object of the invention is to produce a 1 device which shall be simple and cheap in its construction and readily operative.

With these objects in view the invention consists in the stem of a pipe, a cigar-holder, or cigaretteholder so formed as to be capable of operation to force a cleansingliquid either by pressure or by suction through the parts which are liable to become clogged or injured by the accumulation of nicotine, dust, or small particles of tobacco.

The invention also consists in various novel details of construction of the parts of the pipe, or the like, whereby they are adapted" to coact with the improved attachment to accomplish the objects of the invention.

I have illustrated several embodiments of my invention in the accompanying drawings, in which like letters of reference indicate corresponding parts.

In these drawings, Figure 1 represents a 3 5 syringe attachment forming part of the stem of a pipe. Fig. 2* represents a pipe having combined with its stem the syringe attachment and having its bowl provided with an opening, (closed by a suitable removable plug,) 40 whereby liquid may be drawn in .or be discharged for the purpose of cleansing the parts. Fig. 3 is a sectional view of a pipe having my improved stem attachedthereto, the bowl of the pipe being provided with a saliva-drip ing the drip-cup and to allow the ingress and egress of liquid for the purpose of cleansing. Fig. 4 is a partially-sectional view of a pipe the stem of which is provided with my syringe 5o attachment and has formed with it a socket in which the removable bowl rests, it having also Serial No. 189,156. (No model.)

a projection which enters the center of the bowl and through which the smoke is drawn. Fig. 5 is a sectional view of a pipe stem and bowl, the stem being provided with my syringe attachment and with a valve-plug in its lower end, whereby liquid may be admitted with-' out removing the plug entirely, this stem being also provided with ascrew-threaded socket,

in which the bowl of the pipe rests, and with a perforated projection extending from the socket into the bowl. Fig. 6 is a sectional view of a stem for pipes, cigar-holders, or cigaretteholders, consisting of telescoping syringe-sections; and Fig. 7 is a side elevation, partly in section, of a cigar or cigarette 'holder made in accordance with myinvention.

It is a great desideratum in articles in which tobacco is smoked that there be rapid and cheap means of freeing those parts through 73 which the smoke passes from accumulation of nicotine, dust, and small particles of tobacco. Various devices for this purpose have been devised, among which may be mentioned the re movable plug or drip-cup placed in the bot- 75 tom of a bowl, and which is intended to receive drippings of saliva or any nicotine which may be formed in the pipe; but-such device only accomplishes the cleaning of the parts situated near the plug and does not remove8o the accumulation from the stem.

By the device now to be described all objectionable matter which accumulates in any part ofthe pipe, cigar-holder, or cigarette holder may readily be removed by employing 8 5 it to introduce a suit-able cleansing-'liquid such as the solution of an alkali, alcohol, or the likeand thoroughly rinsing the parts therewith.

In the drawings, A represents the barrel of 0" the syringe, in which is arranged a piston, B, by the moving up and down of which the liquid may be drawn in and expelled.

The preferred embodiment of my device, and that which is shown in the figures of the drawings, consists in a stem for articles in which tobacco is smoked, having combined with it a piston the rod of which is provided with a' longitudinal opening to allow the smoke to pass. The piston is madeto perform its func- I00 tion to draw in or expel liquid by stopping the opening in its rod in any suitable manner-as by placing the finger over it, and drawing the rod back and forth in the barrel or tubular part of the pipe. The most simple form of this embodiment is shown in Figs. 2 and 3 of the drawings. In these figures, A represents the hollow stem of the pipe; B, the piston,and C the bowl. The upper end of the stem proper is closed by a cap, a, having a central passage through it, in which the tube 1) rests and slides. This tube is provided at its lower end with a head, I), which fits snugly in the stem A, so that when the opening of the rod is closed and the head is moved back and forth liquid may be sucked into and expelled from the pipestem A. The head I) is made of any material which will not be affected by alkali or other substance which may be applied to clean the stem, and is also preferably made of material not affected by heatas, for instance, of asbestusso that after the pipe has been cleaned the head may be removed,and itself be cleaned by the application of fire. The upper end of the tubular rod 1) is provided with'the mouthpiece b", the opening in which registers with that in the tubular rod and forms a direct conduit for the smoke. The lower end of the stem may be attached to the bowl of the pipe in any suitable or desired manner-as by means of screw-threads,or by a flexible plug attached to the lower end of the stem. This latter form is preferable for some reasons, because it onables the stem to be made and sold separately from the bowls, and to be applied to bowls of different sizes, sufficient compression of the elastic plug being possible to insure fits with the ordinary or most usual sizes of bowls.

In most cases it is not necessary, nor is it often even advisable,thatliquid be introduced into the bowl proper or chamber in which the tobacco is burned; and therefore, in order to provide for the admission of liquid at such a point as to facilitate the cleaning of all of the conduit through which the smoke passes, and that alone, the lower end of the bowl is provided with an opening, in which is placed a removable screw-cap, c. This cap may be of any convenient form, and when it is desired to admit liquid without removing the cap entirely from the bowl the form of cap shown more particularly in Fig. 5 may be employed. In this form of cap the screwthreaded portion which enters the bowl is made hollow, and is provided with a series of holes, 0, reaching from its circumference to its interior, and these holes are placed in such position that they will be exposed when the cap is screwed out a short distance. Although I have particularly described this cap as being applied to the lower side of the bowl,obviously it may be placed in any position where it is desirable that liquid be admitted to clean the smoke-conduit. For instance, in Fig. 5 the stem of the pipe is extended horizontally nearly the whole width of the pi ebowl, and

the opening in which the plug rests and through which the liquid is admitted is in the outer end of the stem. In this form,also, the upper end of the horizontal portion of the stem is provided with a socket, d, which may be screwthreaded on its interior face, or be smooth, as shown in Fig. 4, and up through the middle of this socketis a projection, d, which is tubular,to allow the passage of the smoke from the bowl D, which is so formed as to fit snugly into the socket, and is provided with an opening in its bottom, through which the projection d passes.

Besides the advantage of the device for readily cleaning the pipe, my invention has another, and that is the ability to increase the length of the stem by simply drawing out the piston-rod. Vhen, however, it is desired to use the stem of one length only, the screw-cap a may be provided with a scrcwthreaded socket, to, and the lower end of the mouth piece with an externally-reduced screw-threaded portion, b which can be secured in the socket, and thus the parts can be retained firmly in place to form a stem of minimum length.

A stem capable of being extended to any desirable length may be made by forming a series of hollow pistons, one within another, the innermost one being provided with a protruding mouth-piece, and the top of each piston-rod being provided with a screw-threaded cap having a socket into which enters the cap of the next smaller piston, all as shown in Fig. 6 of the drawings.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. A cleaning device constituting part of a tobacco-smoking implement, consisting of a stem a portion of which is in the form of a piston, whereby liquid may be drawn in and expelled for the purpose of cleansing, substantially as set forth.

2. A cleansing device constituting part of a tobacco-smoking implement, and consisting of a stem having an internal hollow portion provided with a piston, whereby passage for the smoke and means for sucking in and ejecting liquid are formed, substantially as described.

3. A cleaning device constituting part of a tobacco-smoking implement, and consisting of a stem provided with an internal hollow portion bearing a piston and having a mouthpiece formed with or attached thereto, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
